I am using the latest aoscp n rom, I do have twrp N 3.2.2 preview. My computer crashed and i lost my salt MM modem backup. I downloaded the h812 20z modem zip from steadfasters github and flashed it with twrp along with the os and gapps. Phone hangs after LG logo when it says android where it's supposed to lighten and darken. Android stays white after a few seconds the screen goes dark and the message indicator light goes blue. I download an MM build and extracted the 20x modem bin from it but I'm not sure how to flash it with fastboot maybe it will work because the 20z doesn't. Thanks again for your help!! I'm sorry i just want to get my phone working again without spending $$$ for a new one.
Latest TWRP preview image is 3.2.3: http://leech.binbash.it:8008/TWRP/N/
To boot into fastboot mode, see the Changes in behavior in the UsU thread. Use the following command:
fastboot flash modem modem.image
in your asb/fastboot sdk folder.
Refer to: FAQ #22 in the FAQ's in the UsU thread and if you're still having problems go into IRC and get some help directly from steadfasterX.
